CHlMNEY-COWL.

EPECIFICATION forming part of Letters Patent No. 337,022. dated March 2,1886.

Application filed July 25, 1885. Serial No. 172,621. (No model.)

To all whom it may concern.-

Be it known that I, HENRY FRANK SEI- DEL, of the city, county, and Stateof New York, have invented certain new and useful Improvements inGhimney-Gowls, of which the following is'a specification.

This invention has reference to an improvel chimney-cowl by which thedraft of the chimney is kept up whatever be the direction of the wind;and the invention consists of a chimney-cowl consisting of a basesecured to the chimney and of an interior truncated portion attached tothe base and provided with openings or recesses at the lower corners, soas to form escape-openings for the smoke.

The base is provided with a cap, side openings, and outwardly-bentdeflecting flanges, for admitting the wind and carrying it with thesmoke in. upward and outward direction.

The upper part of the interior truncated portion is surrounded withsquare portions having caps, side openings, and flanges below said caps,the uppermost cap covering also the upper end of the interior trunk.

In the accompanying drawings, Figure 1 represents a side elevation, Fig.2 a vertical central section, and Fig. 3a horizontal section, of myimproved ehimney-cowl,on line :6 00, Fig. 2.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the base of my improved chimney-cowl,which is secured in any suitable manner to the chimney, ventilator, orair-shaft.

The base A is provided at its upper end with a cap, B, with sideopenings, a, below the cap, and with outwardly-bent deflecting flangesb.

To the inside of the base A is rigidly applied a truncated portion, 0,which gradually diminishes in width toward the upper end, and which isprovided at the lower corners with openings at d, through which thesmoke can escape, so as to pass in upward direction into the spacebetween the truncated portion 0 and walls of the base and through theopenings on a to the outside of the cowl.

On the cap 13 and a vertical extension of the same is supported the toppart of the cow], which consists of one or more square portions, D D,having caps E E, side openings, e e, and outwardly bent deflectingflangesff below said caps in a manner similar to the base A.The-uppermost cap, E, forms at the same time the cover or crown for theupper end of the truncated portion G.

The truncated portion is provided at that part inclosed by the squareportion D with corner openings or recesses, g that are formed byoutwardly-bent flanges g 9, (shown in Figs. 2 and 3,),which openingsfacilitate the outward passage of the smoke from the trunk G into thespace between itand the surrounding portion D, so as to expose it to theaction of the wind entering through the side openings, e e, and permitthe smoke to pass off with the wind. The smoke that passes to the upperpart of the trunk escapes through the side openings, 6, below the topcap to the outside.

' The caps B and E serve to catch the wind and conduct the same throughthe side openings partly around the trunk O and partly in upwarddirection, so as to produce a suction on the smoke in the chimney andcarry it in upward and outward direction.

My improved chimney-cowl secures a reliable draft for chimneys,skylights, air-shafts, 8m, whatever be the direction of the wind andcondition of the atmosphere, owing to the suctidn exerted by the windand the facility by which the smoke can escape from the interiorconducting-trunk to the atmosphere.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A chimney-cowl consisting of a base having a capand openings and outwardlybent flanges below said cap, an interiortruncated portion attachedto the base and provided with corner openingsat the lower end, and a top part formed of one or more boxshapedportions having caps and side openings and outwardly-bent flanges belowsaid caps, substantially as set forth.

2. A chimney-cowl consisting of a base having a cap and openings andoutwardlybent flanges below said caps, an interior truncated portionattached to the base and provided with corner openings at the lower andIn testimony that I claim the foregoing as my invention I have signed myname in presonce of two subscribing witnesses.
